成唯識論演祕 1.694

1.694

有義：但是常者即非所作；若是無常即有二種。有法無常皆是所作，無說「無常即非所作」，無說「無體不可作」故。但非「恒無」名無常也，《疏》言無說「所作非作」，此義將非。

One interpretation says: Whatever is eternal is unproduced; if it is impermanent, there are two kinds. Existent dharmas that are impermanent are all produced. The statement 'impermanent means unproduced' cannot be made, because that which is non-existent has no substantial entity and cannot be produced. It is only that what is not 'constantly non-existent' is called impermanent. The Commentary's claim that there is no statement of 'produced and unproduced' would seem to be mistaken.
